A direct drive attachment is now available for the T1255 Terrain Leveler surface excavation machine. A patented drum tilt system allows control of grade in both the lateral and longitudinal directions. The unit can dig up to 27 in. deep and 12 ft. wide in a single pass.
The direct drive system features a hydraulic low-speed motor on each side of the cutter head that provides direct drive power to the cutter drum. This ensures a more efficient transfer of power to the cutter drum to help increase production efficiency even in harder mineral substances and overburden.
Top-down cutting allows the cutter teeth to gain penetration without using the machine's tractive effort to drive the teeth into the minerals. As the unit travels forward and the drum rotates, the teeth on top of the drum advance over the top of the mineral surface. As the teeth come down toward the mineral surface, they make contact by impacting the mineral. Operators can also optimize material size.
